Abstract
AbstractThe insecticidal activity of 38 commercialized pesticides against Atractomorpha lata nymphs in Korea was studied. Seven pesticides showed greater than 70% insecticidal activity against A. lata nymphs after 48 h of treatment, and similar results were observed for adult A. lata using the spray method. The insecticidal activity of the seven pesticides, except for thiacloprid, against Oxya sinuosa adults was similar to that against A. lata. Clothianidin, tetraniliprole, and thiacloprid showed higher toxicity when plants and insects were treated together than when insects were treated directly, indicating that pesticides have ingestion toxicity against A. lata. Clothianidin and thiacloprid have been observed to have knockdown effects on both A. lata nymphs and adults. Tetraniliprole showed 86.7% mortality until 7 days after treatment in the residual effect test of pesticide exposure under field conditions.Therefore, this study provides basic data for A. lata control; tetraniliprole was found to be an effective insecticide for the control of A. lata nymphs and adults.
